tEach. of the plates '10 isprovided with a projecting portion 12. which forms a guide nerfaces of the sashes 13 and 15 for wedg- .tures 22 are provided with notches to present suitable. tool or finger-engaging I ers 21 against movement toward the plate 10.?)

for-the outer face of a sash-13, a detachable sash-parting strip 14 which forms both a guide forthe inner face of the sash 13 and a guide for the outer face of another sash 15,

and a detachable curtain-guiding strip 16 which forms a guide for the inner face of the sash 15. Thestrips 14 and 16 are of channel :formationand are cupped againstthe plates 10 with the outer and inner edges of the strip '14 and the outer edge of the strip 16seated in shallow grooves 17 in the plate.

The retaining strips 14 and 16 are provided on their backs with lockracks 18 which are arranged obliquely with respect to the in- F ing coaction with the beveled noses 19 of the locks; 2( carried by: the sashes. The retainingstrips are held in place by fasteners 21 which are mountedin apertures 22 in the .backs ofthe strips and areprovided with heads 23 which extend through and in- .terlock withkeyhole slots 24 in the plate .10. The portions .of the fasteners v21 WVhlCll. ,are exposed through the apersurfaces and the apertures 22 are vertically elongated to permitthe fasteners 21 to be shifted longitudinally of the retaining strips in being moved into or out of latching ,positlon. The fasteners 21 are secured injaperturesk26 in vertically extending leafsprings 27, and thev upper and lower ends of the springs 27 are provided withslots 28 through which headed studs 29 on the strips extends. The slots 28 and studs 29 permit the fasteners 21 and springs 27 to move upwardly or downwardly, and the resistance of the springs 27 to flexing tends to resiliently hold the fasten- The heads 23 of the fasteners are provided with beveled surfaces 30, and the lower narrow ends of the keyhole slots 24 are correspondingly countersunk at 31 whereby to permit the heads 23 to seat in the narrow coun tersunk ends of the slots and yieldingly resist dislodgment.

In order to latch one of the fasteners 21, the, notched end 25 thereof is engaged and shifted into the upper end of the slot 22,

in which position the head 23 of the fastener will he in register with the enlarged upper end of the keyhole slot 24 in the plate 10. Then the fastener 21 is pressed toward the plate 10 against the yielding resistance of the spring 27 into a position wherein the head 23 projects through the enlarged end of the slot 24. After this has been done, the fastener 21, with the pressure still applied thereto, is forced downwardly, causing the head 23 to move into an interlocking position opposite the narrow end of the slot 24, in which position, when released, it will snap back into the countersink provided for the same. The fasteners 21 make it easy to either apply or remove the retaining strips, and serve to hold the strips tightly against the plates without permitting any rattling or leaving objectionable openings therebetween. The proper positioning of the retaining strips is insured by studs 32 which are attached to the inside faces of the backs of the retaining strips and project through apertures 33 in the plates.

The sashes 13 and 15 are provided along their vertical edges with U-shaped wear strips 34 which are detachably secured in position by studs 35. The studs are carried by the backs of the wear strips and project through apertures in the sashes into vertically interlocking relation with the latter. The wear strips are preferably made of sheet spring brass and hug the sash when applied thereto. The outer edges of the wear strips are provided with outwardly turned flanges 36. The flange on the wear strip on the outer sash 13 projects beyond the surface 37 on the projecting plate portion 12, while the flange on the wear strip on the inner sash 15 projects beyond the surface 38 on the retaining strip 14, whereby to provide weather proofing shields. The wear strips 34 are provided on the outer portions thereof with thin spring brass strips 39 which bear resiliently against the above mentioned guide surfaces 37 and 38, and are also provided, alongside the strips 39, with pile fabric strips 40 which are arranged with the pile directed outwardly into substantially perpendicular engagement with opposed guide surfaces 41 and 42 presented respectively by the projecting portion 12 of the plate and the inner wall of the retaining strip 14. The spring strips 39 and the pile fabric strips 40 are pressed outwardly against the opposed guide surfaces by the outwardly wedging action of the locks 20, whereby to produce a weatherproof and noiseless form of engagement therewith while permitting the sash-es to be easily released and raised or lowered.

Each of the lock racks 18 is provided with a long series of closely arranged recesses 43 mto two of which the bifurcated nose 19 of the lock is adapted to project. The recesses are provided with abrupt top and bottom walls 44 which prevent the sash from being either raised or lowered except when the lock is released. The front faces of the teeth 45 which are formed between the recesses 43 are undercut at an inclination. The inclination referred to permits the spring-pressed nose of the lock to quickly work its way outwardly into the recesses 43 when the sash is dropped, but such inclination is not carried far enough back to eliminate or interfere in any way with the interlocking function of the top walls of the recesses.

I claim:

1. In sash construction, the combination with a vertically slidable sash, of a side plate having a projecting guide portion in lapped relation to one face of the sash and two spaced positioning grooves beyond the other face of the sash, and a sheet metal guide strip of U-shaped cross section detachably secured to the plate with the edges of the strip seated in the grooves.

2. In sash construction, the combination with a vertically slidable sash, of a side plate having a projecting guide portion in lapped relation to one face of the sash, a guide strip positioned against the plate adjacent the other face of the sash, means for preventing sidewise movement of the strip when positioned against the plate, and a plurality of vertically shiftable stud mounted in the strip and provided with heads for interlocking coaction with the edges of slots in the plate when the strip is positioned against the plate.

3. In sash construction, the combination with a vertically slidable sash, of a side plate having a projecting guide portion in lapped relation to one face of the sash, a guide strip positioned against the plate adjacent the other face of the sash, means for prevent ing sidewise movement of the strip when positioned against the plate, a plurality of vertically shiftable studs mounted in the strip and provided with heads for interlocking coaction with the edges of the slots in the plate when the strip is positioned against the plate, and spring means for drawing the heads of the studs tightly against the edges of the slots.

4. In sash construction, the combination with a vertically slidable sash, of a side plate having a projecting guide portion in lapped relation to one face of the sash, a guide strip positioned against the plate adjacent the other face of the sash, means for preventing sidewise movement of the strip when positioned against the plate, a plurality of vertically shiftable studs mounted in the strip and provided with heads for interlocking coaction with the edges of keyhole slots in the plate when the strip is positioned against the plate, and spring means for drawing the heads of the studs tightly against the edges of the narrow portions of the slots.

5. In sash construction, the combination with a vertically slidable sash, of a side plate having a projecting guide portion in lapped relation to one face of the sash, a guide strip positioned against the plate adjacent the other face of the sash, means for preventing sidewise movement of the strip when positioned against the plate, a plurality of vertically shiftable studs mounted in the strip and provided with heads for interlocking coaction with the edges of keyhole slots in the plate when the strip is positioned against the plate, and spring means for drawing the heads of the studs tightly against the edges of the narrow portions of the slots, the portions of the heads of the studs which engage with the edges of the slots being of conical formation, and the edges of the lower ends of the slots being correspondingly countersunk to fit therewith.

In witness whereof I have hereunto subscribed my name. 25 WILLIAM S. HAMM.
